When to plant Yellow Archangel?

Yellow archangel thrives in partial to full shade, making it an excellent choice for difficult shady spots under trees or along north-facing borders. It tolerates a range of soil types but performs best in loam or clay soil that retains moisture without becoming waterlogged. Before planting, clear the area thoroughly of weeds—this groundcover spreads vigorously and can be difficult to weed once established. Plant yellow archangel in March, April, May, September, or October when the soil is workable and temperatures are mild. Autumn planting allows roots to establish over winter, while spring planting gives a full growing season ahead. Dig holes slightly larger than the root ball and space plants 50 cm apart; they will fill in quickly thanks to their spreading habit via stolons (creeping stems that root at the nodes). Set each plant at the same depth it was growing in its pot, firm the soil gently around the roots, and water thoroughly to settle the soil and eliminate air pockets. If planting on a slope or under trees where soil may be dry, incorporate well-rotted compost or leaf mould into the planting area to improve moisture retention. After planting, water regularly for the first few weeks until plants are established and showing new growth. A 5 cm layer of organic mulch such as leaf mould or composted bark around (but not touching) the stems will help retain moisture and suppress weeds while the groundcover fills in. Be aware that yellow archangel can be invasive in favourable conditions, so consider whether its vigorous spread suits your garden before planting near more delicate perennials.
